pagemap: add page-types tool

2009-06-17T02:47:38+00:00

Add page-types, a handy tool for querying page flags.

It will expand some of the overloaded flags:
	PG_slob_free   = PG_private
	PG_slub_frozen = PG_active
	PG_slub_debug  = PG_error
	PG_readahead   = PG_reclaim

and mask out obscure flags except in -raw mode:
	PG_reserved
	PG_mlocked
	PG_mappedtodisk
	PG_private
	PG_private_2
	PG_owner_priv_1
	PG_arch_1
	PG_uncached
	PG_compound* for non hugeTLB pages

inclusive.

page allocator: use allocation flags as an index to the zone watermark

2009-06-17T02:47:35+00:00

ALLOC_WMARK_MIN, ALLOC_WMARK_LOW and ALLOC_WMARK_HIGH determin whether
pages_min, pages_low or pages_high is used as the zone watermark when
allocating the pages.  Two branches in the allocator hotpath determine
which watermark to use.

This patch uses the flags as an array index into a watermark array that is
indexed with WMARK_* defines accessed via helpers.  All call sites that
use zone->pages_* are updated to use the helpers for accessing the values
and the array offsets for setting.

mm: add documentation describing what tsk->active_mm means vs tsk->mm

2009-04-13T22:04:32+00:00

I'm sure everyone knows this, but I didn't, so I googled it, and found a
nice explanation from Linus.  Might be worth sticking in Documentation.

tracing: consolidate documents

2009-04-09T05:28:10+00:00

Move kmemtrace.txt, tracepoints.txt, ftrace.txt and mmiotrace.txt to
the new trace/ directory.

I didnt find any references to those documents in both source
files and documents, so no extra work needs to be done.

trivial: fix where cgroup documentation is not correctly referred to

2009-03-30T13:22:02+00:00

cgroup documentation was moved to Documentation/cgroups/. There are some
places that still refer to Documentation/controllers/,
Documentation/cgroups.txt and Documentation/cpusets.txt. Fix those.
